SPECIFICATION forming part of Letters Patent No. 773,700, dated November 1, 1904. Application filed May 15, 1902. Serial No. 107,432. (No model.)

T on /2/0771 Lt nuty concern.-

Be it known that we, CHARLES F. AMES and HENRY A. RnARsoN, of Rochester, in the county of Monroe and State of New York, have 5 invented certain new and useful Improvements in Cameras; and we do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of To this specification, and to the reference-numerals marked thereon.

Our present invention relates to cameras, and particularly to that class known as rollholders or film-cameras, in which a car tridge composed of a continuous strip of sensitized film or'paper is employed and which is arranged in a roll or upon a spool carried at one side of the camera and transferred or wound upon a similar spool upon the oppo-- site side as successive exposures are made.

Our invention has for its object to provide a camera in which rolls of sensitized film or paper may be employed and which is so constructed that the film or paper may be moved 5 out of alinement with the lens and a focusingscreen which will be moved, preferably automatically operated, by the movement of such parts to permit the lens to be first prop erly focused before an exposure is made.

To these and other ends the invention consists in certain improvements hereinafter described, the novel features being pointed out in the claims at the end of this specification.

In the drawings, Figure 1 is a longitudinal 3 5 sectional View of a camera constructed in accordance with our invention, showing the parts in the normal position for making an exposure. Fig. 2 is a similar view showing the film or roll-holder in the elevated position.

Fig. 3 is an enlarged perspective view of the rear side of the camera, showing the rear cover of the roll-holder removed. Fig. I is a cross-sectional View on the line as w of Fig. 1. Fig. 5 is a vertical sectional view on the line 3/ y of Fig. 4, and Fig. 6 is a horizontal sectional View on the line .2 2 of Fig. 2.

Similar reference-numerals in the several figures indicate similar parts.

A camera embodying our improvements embodies a casmg having the forward and rear sides 1 and 2, respectively, and the latter is provided with acentral aperture 3, which is normally closed by a drop front or door 4. In the several figures the door is shown in the open position, and on its upper side it is provided with ways 5, upon which is mounted a sliding supporting-frame 6, carrying the lens-casing 7. Extending rearwardly from the aperture in the front 2 is a recess or chamber having the side walls 8 and the rear wall or frame 9 containing the exposureaperture, and to this frame is attached the rear end of the usual collapsible bellows 10, which is also connected at its forward end to the lens-casing 7.

In order that the film-spools and the film may be moved out of alinement with the exposure-aperture in the wall 9, they are mounted in a separately vertically movable roll holder or casing, which latter embodies the film-chamber 15 at one end and the receivingchamber 16 at the opposite end, said chambers being arranged at opposite sides of the recess in the main casing, and they are connected by means of a vertically-extending wall 18, lying in the rear of the wall 9 and provided with a similar aperture, and over the tops of the chambers extends a top portion or cover 19. The sensitized film or paper, preferably the ordinary cartridge-film embodying a strip of film and a cover of opaque paper, is upon the spool 22, located in the chamber 15, and extends across the rear side of the wall 18 over small rollers or idlers 2 1 at the ends of the wall, and it is received upon the windingspool 23 in the chamber 16, as shown particularly in Fig. 4:. Suitable centering and securing devices for the spools are provided, and in the chamber 16 is a key 11 accessible from the exterior and adapted to engage the upper end of the winding-spool 23. The lower end of the spool is engaged bya centering-pin 12 on' a vertically-movable arm 13, sliding in ways orguides 14: and held in the normal position by a spring 17. The rear side of the supplemental casing or roll -holder is proback portion 3) of the exterior casin vided with a removable back 25 lower edge a tongue 6, engaging a suitable groove formed in the rearwardly-extending havin at its lip 27 at the lower end of the wall 18, and at i lightto theinterior of the holderis eflectually prevented. In order to secure the back 25 in its normal position, a simple locking device, such as illustrated in Fig. 6, is provided, consistingof a bar 30, having rearwardly-extending arms 31, provided with hooks or projections 32 at their ends adapted to engage beneath the edges of plates 33, secured upon the interior of the back portion.

H indicates an operatinglip or extension on the bar 30, arranged centrally between the lilm-chainbers, whereby the bar may be operated to disengage the hooks or projections 32 from the plates 33 and with which they are normally held in contact by means ofa spring 35, operating the bar in one direction, as shown. In order that the portion of film extending between the chambers and across the aperture in the wall 18 may be protected when the roll-holder is elevated or moved out of line with the lens, we employ a slide 135. This slide operates vertically through an aperture in the top 19, and grooves or channels 36 are arranged in the wall at the sides and bottom of the aperture, so that when the slide is down, as shown in Figs. 2 and 3, the aperture in said wall is elfectually closed. At the upper end of the slide is provided a loop or handle 56, by means of which it may be elevated and removed from in front of the film; but as it is unnecessary that the slide be removed entirely from the casing a stop in the form of a pin 37 is provided to limit its up ward movement. For the convenience o the operator in manipulatingthe camera the slide is provided at about its middle point with hinged or jointed sections 38, whereby it may be folded down upon the top of the casing when it is withdrawn.

The roll-holder or supplemental casing may be guided in its vertical movementin any suitable manner, and in the present instance tongues or guides 39 on the camera-casingare shown engaging ways formed in the rollholder outside and forward of the spool-chambers, and in the inner sides of the latter are similar recesses in which engage tongues s1, projecting outwardly from the edges of the The roll-holder is held in its upper and lower positions by means of a spring-operated latch 42, having the end tifl, adapted to engage a recess 4a in the lower end of the plate -15 at one end of the roll-holder casing to hold thelatter in the elevated position when focusing, and also adapted to engage a similar recess tij to retain the casing when in the lower or picture-taking position. The latch a2 is pivoted at t? and is also provided with a button or head 48, whereby it may be conveniently operated from the exterior of the main casing to disengage its operating end 43, and, if desired, permit its entire removal.

In order that the operator may determine when the lens is properly focused, a groundfocusing screen 50, supported in a frame 51. is adapted to be projected in the plane of the sensitized film when the supplemental casing is moved upwardly, and to accomplish this object the frame is supported at its ends upon arms or links 52. Theselinks are capable of a parallel movement and are pivoted to the upper and lower side of the frame, and are also pivoted upon brackets 53, located at the side of a recess 54, formed at the inner side of the portion 1 of the main casing. The focusing-screen normally lies in this recess, as shown in Figs. 1 and 4:; but when the rollholder casing is moved from its position of use it is projected beneath the latter by means of a spring 55. Small steps or projections 56 on the brackets 53, engaging the arms 52, limit its inward movement, so that the sur face of the screen is accurately positioned, as will be understood. In rear of the aperture or recess 5st is arranged a door olnclosure 5T, hinged at its lower end and adapted to be opened outwardly. as shown particularly in Fig". 3, to expose the screen so that the operator may have a clear and unobstructed view while adjusting the lens relatively thereto in order that a clear-cut and accurately-delined picture may be obtained. The focusing-screen is projected beneath the roll-holder by the spring 55, as described and shown particularly in Fig. 2, and to cause it to be automatically returned to its normal position the lower edge of said wall and the cooperating upper edge of the frame 51 is beveled, so that when the holder is moved downwardly the focusing=screen will be moved rearwardly upon the links or supporting-arms 52, and as the back of the holder passes over the frame 51 it will be held in the recess 5t until the holder is again removed.

A camera such as we have shown and described, embodying the roll-holder provided in a separate casing which may be moved out of alinement with the lens, enables a focusingscreen to be employed, so that the operator may determine not only the size of the picture he can obtain, but he will be guided in locating any particular object at the exact point upon the negative that he may desire. Further, he will be guided in the adjustment of the lens relatively to the screen to produce a clear and distinct image thereon, which will be subsequently produced upon the negative when the parts are returned to their normal position and the proper exposure is made.

The roll-holder is so arranged in the camera that it occupies but little room and does not interfere with the focusing operation, and

IOC

IIO

while it is intended to remain as a part of the camera it may be removed, if desired, for reloading, although this is not necessary, as the back cover may be removed for the purpose when the holder is elevated, as shown in Fig. 3. The markings on the back of the paper covering of the film may be inspected through a suitable aperture formed in the rear cover or door 25, as is usual in cartridge-cameras.
